Cant change menu background

I just installed the newest version on PM3 HD and I wanted to change the menu backgrounds and the only menu I can not change is Movies. I can go through and select the picture and when I hit ok it stays as the default picture

Thank you. I was begining to wonder if i was going nuts. Im still new to the xbmc htpc thing. and out of all the skins this is the easiest and prettiest for a nublet to use. everything is straight forward. thank you
